용도

Benzyltriethylammonium chloride is used as a catalyst in the preparation of 2-phenylbutyronitrile from phenyl acetonitrile. It is involved in the Knoevenagel condensation of carbonyl compounds with active methylene compounds to give olefinic products. It acts as a phase transfer catalyst used in the alkylation reaction. It reacts with 1H-Pyridine-2-thione to get 2-Benzylsulfanyl-pyridine.

참고

Store in cool place. Hygroscopic. Incompatible with strong oxidizing agents.

Phase-transfer catalyst (see Appendix 2) which has found wide application in the generation of carbenes from haloforms and related precursors: Org. Synth. Coll., 7, 12 (1990); 8, 223 (1993). Dihalocarbenes have been used to convert primary amines (t-butylamine) to isonitriles: Org. Synth. Coll., 6, 232 (1988), and in the dehydration of amides, thioamides and oximes to nitriles: Tetrahedron Lett., 2121 (1973). Ureas give cyanamides.

For use in the formation of polysubstituted cyclopropanes by carbene-type addition to double bonds, see Ethyl­ chloroacetate, A15554.

For use in the dialkylation of malonate esters to give cyclopropane derivatives, see: Synthesis, 54 (1985); Org. Synth. Coll., 7, 411 (1993).

In combination with NaBr in acetonitrile, has been used for the mono-dealkylation of phosphonate diesters: Synthesis, 453 (1983).
